There is no panic about the (US) Post Office. The agency is under concerted attack by the President's men, and has already suffered serious damage. The President has explained in detail that a well-operating Post Office would prevent his re-election by delivering mail-in ballots favoring his opponent, and has acted to stop it.
Can anyone with real knowledge of the subject corroborate or dispute this? Genuinely interested. The article makes a lot of sense, and if true, disputes the popular narrative. But there is a big "if" and I am not qualified to know if this is true (hopefully) or just really well crafted to hide the truth.
